QUADDING APPARATUS 0F TYPOGRAPHICAL OOMPOSING-MACHINES.

Application filed November 23, 1907.

To all whom it may concern:

Be it known that we, CHAnLns Snowman VVooDRoFrE, residing at 188 Fleetstreet, in the city of London, England, and HERBERT both residing at theLinotype and Machinery Vorks, Broadheath, in the county of Chester,England, all subjects of the King of the United Kingdom of Great Britainand Ireland, have invented new and useful Improvements in the QuaddingApparatus of Typographical Composing-Machines, of which the followingisa specification.

The present invention relates to improvements in the quadding apparatusof typographical composing machines, more especially in the quaddingapparatus described in the specification of Letters Patent 608155.

That apparatus was invented for use in and is described in connectionwith the linotype machine described in the s ecification of LettersPatent 436532. In thls machine the mold for the body of the linotype isa horizontal slot in a mold block on the mold carrier, that for theprinting edge of the linotype being provided by the assembled line ofelements or matrices and space bars. This line is held against the bodymold by a vise consisting of two jawsbetween which the line is wedgedtight by the thickening of each of the space bars. The body mold is ofthe same length as the line, so that the latter covers and closes thebody mold on that side of it, the opposite side of it being open toreceive type metal which is injected into it by a pump. If the line tobe assembled happened to be a short one such as so frequently occurs atthe end of a paragraph, the operator was obliged, unless 1118 machinewas fitted with the quadding apparatus of Patent 608155, to make theshort line up to full length by assembling asufficient number ofpression of and therefore occupied time for which there quads, otherwisethe line would not have been long enough to close the mold. Theassembling'of each quad necessitated a dethe quad key on the keyboardSpecification of Letters Patent.

been invented for use in the same machineand is articularly adapted foruse therein althoug it is not necessarily restricted thereto. Butbecause of that particular adaptability, its construction for and use inthe said machine have been chosen for illustration and specification. Itfollows Patent 608155 in having the vise jaw that contacts with the endof a line, movable, but is characterized by certain improvements whichare duly specified herein and claimed.

Before proceeding with the specification of such construction anduse,tit will be well to premise that the matrices and space bars-thesebeing the elements which the said machine composes or assembles intolinesenter a horizontally positioned organ known as the'assemblerelevator through the open right hand end of it, one by one; that theyare pushed along the said elevator toward the left by the last elementassembled; that the elevator then assuming the function of aline-carriage, is raised vertically till it places the line assembled init within the grasp of the line-shifter; that the line- I is wedged by.them tightly between the said jaws; that the casting apparatus has aslot w to serve as a mold for the body of the linotype, the only part ofthe complete mold which the asembled line contributes, being that forthe printing edge of the linotype; that these twoslot and partregisterwith each other to form the complete mold; that the linotype is thencast; that the vise is then opened'as much as it had. been previouslyclosed; and that, lastly,th'e said first elevator with the line'in it,is raised vertically to deliver the line to the distributing the onethat contacts with the end of a linemechanism.

Referring to the accompanying. draw- 1ngs:-F1gure 1 is a frontelevation, the full "lines showing the assembler elevator in thesame'line-shifter with the same line in it in position'to cooperate withthe first elevator, and the dotted lines showing the same line in thecasting position: Fig. 1 is a front elevation or edge view of a modifiedform of the spring bar 42 seen in Fig. 1.

1, 1 are parts of the machine frame; 2, the assemb er elevator; 3, thedetaining pawls at its entrance mouth; 4:, the star wheel; 5, the lineresistant fast on the left hand end of the assembler slide 6, and whichis moved from the entrance mouth of the elevator 2 to the left by thefirst element of the line bein assembled; 7, the left hand and 8,the'rlght hand finger of the lineshifter that receives the assembledline from the elevator 2 and is then moved by a lever not shown in thefigures, to the leftwith the line in its grasp, to deliver it into theelevatornext mentioned. each finger being mounted on its own slide sothat each can move in both directions independently of the other, thefinger 7 being returned to its' original position by a spring 9'.-Fig.2--- pulling on its slide 10 from a fixed pomt on the frame 1, and thefinger 8 by the said g lever; 11, the first elevator capable of avertical motion in, both directions in suitable guides in the vise frame12 which is hinged by its bottom to the machine frame in order that itmay be swung down'to the front to expose the frontface of the moldcarrier 13 and of the mold slot 14 in the mold block on it (not shown)and .also'the rear face of the vise frame 12; 15, the vise top faston'the vise frame 12; 16, the left hand vise jaw and 17 the right handvise jaw (known as the quadding jaw both carried by the vise top 15, theaw 1 capable of being moved alon the said top 15 toward and away fromthe aw 16 for the purpose of quadding. The rear faces of the two jaws 16and 17 are in the same vertical plane and the front face of the moldslot 14 is in a plane parallel therewith, so that when the mold carrier13 is moved forward into the casting position, the ends of the moldblock bear metal-tight against the respective jaws.

18Fig. 6-is a stop against which the jaw 17 abuts when a normal line, i.a, of full measure, is to be placed between the said two jaws. Theoperation of quadding consists in unlocking the quadding jaw 17,

moving it from its normal position toward 1 bler elevator 2 and past thepawls 3 by the star wheel 4, the first element of the line pushing theline-resistant 5 before it. At one time, it'was the practice to have theshifter finger 7 up to the finger 8 and in contact by its bottom endwith the top of said finger 7 before it to the left, thereby separatingit from its fellow finger 8 by a bled line, no matter how long or shortthat cause it threw all of the work of moving the finger 7 to the left,upon thestar wheel 4. It was replaced by an arrangement by which theoperator could set the finger 7 at the full measure distance from itsfellow finger 8. before .he be an assembling. But it is obvious that a s'ort line 19, i. 6., one that needs quadding, stands at the moment whenthe act of assembling it is complete, between latter being thensomewhere midway of the two ends of the assembler elevator2 and at aredriven through the mouth of the-assemthe resistant 5 so that the latterpushed the distance equal to the measure of the assem- '115 might be.This practice was abandoned be- 1 the star wheel 4 and theline-resistant 5, the

line-resistant 5.

l gers of the line-shifter, not only will the latter be too wide tograsp it, but the leading elements of-the line will fall off their feetto the left, as soon as the line is clear of the Automatic means areprovided by which the finger 7, duly set at a distance from its fellowfinger 8 equal to the measure of a full line, is released by the risingelevator 2 from that setting and pulled by its returning spring 9 up tothe leading element of the line before it has a chance of falling ofiits foot. These means are illustrated in Fig. 1.

20 is a stud projecting from the head of the finger 7; 21, a shifterfinger stop projecting from the right hand end ofa rod 22 and engagingwith the stud 20 so as to prevent the finger 7 moving to the right underthe pull of its returning spring; 23, a socket through which the rod 22can be moved lengthwise in either direction; 24, a set screw for holdingthe rod 22 in any desired position in the socket 23; 25, a bar slidingvertically in either-direction on guides 26, 26, on the machine frame 1and having the socket 23 fast on its top; 27, a spring constantly urgingthe bar 25 upward; 28, a foot on the bottom end of the bar 25; and 29, alug on the adjacent side of the assembler elevator 2. The bar 25 is soproportioned and the lug 29 so positioned, that when the elevator 2 isin the assembling position, the lug 29 stands over the foot 28, therebyholding the bar 25 2 and 3. 30 is a pin projecting rearwardly downagainst the resilience of its spring 27, and the finger 21 in detainingengagement with the stud 20.

The object. of the longitudinal adjustment of the rod 22 by the setscrew 24: in the crosshead 23, is to allow the operator to set thefinger 7 at the full measure distance from its fellow finger 8. It issubstantially the arrangement for this purpose already mentioned and per86 forms no part of the present invention.

The action of the means just described is as follows. As soon as theelevator 2 begins to rise, the lug 29 frees the bar 25 and the spring 27pulls the latter upward, thereby lifting and disengaging the stop 21from the stud 20 on the finger 7. The latter is thereupon pulled by itsreturning spring, to the right up tothe leading element of the risingline 19 which it engages before that element has cleared the resistant 5An alternative means is illustrated in Figs.

from the top of a bell' crank lever 31 fulcrumed at 32 on the frame 1.VVhen-the elevator 2 is in the assembling position, this pin standsimmediately to the right hand of the bottom end of the latter andintersects the path th'ereof thereby preventing the latter from movingto the right under the pull of its returning spring. A shoulder 33 onthe leftf hand side of the elevator 2 engages a foot 34 on the lever 31when it-the elevator-is in the assembling position and thereby makes thesaid lever-hold the pin 30 in retaining engagement with the finger 7against the resilience of a spring 25 which pulls on the top of the saidlever from a fixed point on the machine frame 1, as indicated by thedotted lines in Fig. 2. The arrangement of the parts is such that as theassembler elevator 2 returns into the assembling position frompresenting an assembled line of any length'normal or short-between thefingers 7, 8 of the shifter (and this return is effected while theshifter is still cooperating with the first elevator 11), the shoulder33 engages the foot 34 and rocks the bell crank lever 31 from the fullline position in both Figs. 2 and 3, into the dotted one in Fig. 2against the resilience of the spring 35, thereby placing the pin 30 inthe path of the finger 7 which is accordingly stopped by it as thereturnin spring 9 is returning its slide 10 and it. elevator 2 riseswith a short line 19 init, the spring 35 pulls thepin 30 out of-the pathof the finger 7, whereupon the latter is pulled up to the line 19 by itsspring 9, as shown by the full lines in Fig. 2.

A second alternative means is illustrated in Figs. 4 and 5. 36 isa bellcrank lever fulcrumed at 37 on the machine frame 1 and having ahorizontal arm to serve as the stop for the finger 7; 38; a springholding the said stop in detaining engagement with the finger 7; 39, atail fast on the elevator2; 40, a cam on the top end of the tail 39; 41,a second cam on the bottom end of the lever 36, the parts being soproportioned and positioned that so long as the elevator 2 is in.

s soon as the the assembling position, it holds the cam 4-0 just to therear and clear of the cam i1,

' the said elevator begins to rise, it rocks the said stop 36 downwardout of the path of the finger 7 whichis thereupon pulled by,

its spring 9 up to the line 19, the tail 39 being long enough to keepthe finger stop below the pathof the finger 7 until after the latter haspassed the said stop on its way to cooperate with the first elevator 11,and short enough to clear the cam 41 as the elevator 2 returns to theassembling position, in time for the spring 38 to return the finger stop36 into its operative position before the finger 7 is returned by itsspring 9. If theline 19 is a very short: one, there is a risk of itsfirst element clearing the resistant 5 before the finger .canengage it.

To prevent such an accident, the said fin gersee Fig. 1carries a springbar 42 which projects flamboyantly from it toward the finger 8. 43 Fig.1 is a substitute form of bar. It. is .fast by its bottom end to thefinger 7, carried from that point toward the finger 8, bent backwardtoward the finger 7 andpassed through it. Either form of bar enables thefinger 7 to present a light, curved and yielding support into the upwardpath of the line 19 as it rises, and one which will be in time to catchand support, with some part of its surface, a leading element that maybe falling off its foot by reason of its having cleared the resistant 5before the finger 7 can engage it. t

The above-mentioned specification 608155, shows the quadding jaw as ofthe same length at it was in the machine of Patent 436532 Consequentlyit cannot quad a very short line when the mold slot 14 is a longone, sayems long, because then the jaw 1s not long enough to close metal-tightas much of the slot as the line leaves unclosed. The jaw 17 is longenough, by reason of the prolongation 17 shown in Fig. 6, when it 1s incontact with its fellow jaw 16, to cover the whole of the mold slot 14.According to the present invention, 44 Fig. 6-is a rack on the bottomface of the jaw 17 or on the bottom face of a bar 45 fast to it andtherefore incorporated with it, the teeth of the said rack pointing tojaw 16. j 46 is a pawl pivoted on the vise frame 12 and adapted tobeheld by a spring 47 in engagement with some one tooth on the rack 44to lock the jaw 17 in its normal osition. The quadding jaw 17 isunlocked y disengaging the pawl 46 from the rack 44. Thisdisengagementis efiected by a pro- ,jection 57-Fig. 8carried by the topof I the elevator 11 and which engages the top of a push pin 58vertically mountedin the vise top. 15 and normally standing up above itwith its bottom end resting on the pawl 46, the spring 47 being strongenough to supp'Ort and'raise the p1n 58'as' well as to reengage the pawl46 with the rack. The proection 57 is so situated on the elevator 11that the dlsengagement of the pawl 46 takes place ust before theelevatorll has moved into its lowest position, 6., after-the saidelevator has be 11 to place the short line 19 between the jaws 16, 17,and just before it is in casting register with themold slot 14. But alllines do not require quadding, and for that reason, the operator must beenabled to put the quadder into or out of action. Accordingly, thepresent invention gives him the control of the engagement of 'theprojection 57 with the pin 58, so'that such engagement shall not takeplace when the line in the elevator 11 does not require quadding, andshall take place when ,it

nose of a bolt adapted to slide from front to rear in a socket 59 underthe projecting action of a spring 61 and to be pulled to the front againand locked in that position I by a bayonet joint 62- -F ig. 9. Theoper-' ator pulls the bolt 57 to the front and looks .it whenever theline in the elevator 11 is a normal one and does not therefore requirequadding. If on the other hand, it is a short one and does thereforerequire quadding, he unlocks the joint 62 and the .spring 61 puts thenose of the bolt .57 into the proper position for engaging the pin 58.

The jaw 17 is moved from its normal or full measure position toward thejaw 16 until the short :line .19 is clamped between them,

i. e., intoaquad'ding position, by the following means F-igs; 6 to 8. 48is a weight falling freely to impart the quadding movement to the jaw17. This weight is advanta geously'situated on the left hand side of thevise frame 12. It is connected to the jaw 17 by a cord 49 which beingfast by one end to the'top of the weight 48, is led upward over a pulley50 j ournaled in the vise top 15, from there to the jaw 17 (or to thebar 45) to which it is made fast, thence to the right to and around apulley 5'1 likewise journaled in the vise top 15, thence toward and overa third pulley 52 in the top 15, and from there downward .and around afourth pulley 53 journaled on the first elevator 11 near the foot of itand finally upward to the bottom of the weight 48 where it is made fast.The weight 48 is therefore capable of a vertical movement in bothdirections corresponding with the respective longitudinal movement ofthe-jaw 17. It has lugs 54, 54, engaging in a vertical groove 55 in thevise frame 12 to prevent it-the weight-sagging forward when the saidframe (to which the parts 11 and. 48 to 55 are connected) is swung downto the front. 56 is a spring in a suitable position in the length of thecord 47 to prevent the necessity of very fine adjustment of the saidcord or of the parts'connected-with it. j

j The jaw 17 is locked in quadding position against the well-knownwedging action ex-' erted by the space bars in the line 19 as it is abeing justified, by the engagement of a set of, say three, pawls 63, 64,65Figs. 8 and 9- with a rack 66 on'the top of the said jaw. 1

This rack 66 extends for nearly the full length of the jaw 17, its teethpointing to the right. The pawls 63, 64, 65, are pivoted on a suitablysupported and practieally stationary pm 67 and extend to the left toabut against the'vertical faces of the respective rack teeth. 5 The pin67 is shown as carried by the well known pump. stop lever 68 which hasto be moved by'the justification of any line-short or normal-for.a shortdistance up to the stop 69 as heretofore. 'The pawls 63, 64, 65, are ofdifferent lengths so that if none of them is actually abutting a ainst atooth, the jaw 17 cannot be moved to the right for a distance greaterthan the third of a tooth before one does so abut, and are kept inengagement with the rack 66 for as long as the jaw 17 is to be heldlocked against the above-mentioned wedging action, either by springs70Fig. 6 fiXed to the said jaw or by their own weight. They are raisedout of engagement with the rack 66 to allow of the jaw 17 being returnedto its normal position, and kept out of engagement by a pin 71 which isheld under them between their noses and their pivot pin 67, by a lever72 fulcrumed on the said pivot pin, and nor mally held up by a spring73. This being so, provision must be made to put the pin 71 out ofaction when the line in the elevator 11 to be quadded. .ThisprovisionFig. 8- takes the form of a projection 74 positioned on theelevator 11 to engage the lever 72 so as to put the pin 71 out of actionjust before the jaw 17 must be locked in'the quadding position.

The jaw 17 must be returned up to the stop 18, z. 0., into its normalposition, after each quadded linotype has been cast This return iseffected by raising the weight 48 and therefore pulling the cord 49 inthe reverse direction. 'The weight is raised byan arm 7 5 projectingfrom the bottom end of the elevator 11 and fitted with an adjustment 76to make it begin to raise the weight at the proper moment. The cord 49is practically an endless one having the weight 48 fixed at a suitablepoint in its length and also having two bights in it, one around thepulley 51the one to the side of the jaw 17 opposite to the weight andthe other bight around the pulley 53the one 011 the arm 75 thatmovesdown to pay out cord as the weight pulls the jaw and moves up toreverse the said j aw and lift the weight to pay out cord. Durmg thetime which elapses between the commencement of the rise of the elevator11 to deliver the line in it to the distributing mechanism, and theengagement of the arm 75 with the weight 48, the latter is tending topull the jaw 17 to the left. If it were allowed to do so, the said jawwould strike and injure those portions of any space bars in the line,which hang below their accompanying matrices before the said elevatorhad raised them above the jaw 17.

quadding jaw 17 in quadding position, areshown in Fig. 8 and describedtherewith as being pivoted on a pin 67 that is carried by the pump stoplever 68. A better method of mounting them is shown in Fig. 10.According to it, they are pivoted on a headed pin 77 screwed into ablock 78 fixed upon the vise top 15. The springs 70 are replaced by at-hree-tongued comb spring 79 fixed upon the block 78, so as to pressthe noses of the pawls down into engagement with the rack 66. Theadvantage of this method is as follows. The mold carrier 13 is supportedby a slide (not included in the drawings because it does not form anypart of the present invention) which the operator sometimes wants todraw to the front as far as itwill come. To gain access to it for thispurpose, he pulls down the vise frame 1.2. When the said. pawls aremounted on the lever 68, they are likely to be in the way of the saidslide, but when they are mounted on the vise top 15, the vise frame 12carries them out of the way. The jaw 17 must have a slight movement toand from the right hand to cotiperate with the pump stop in the wellknown way, and which motion, per se is quite independent of the presentinvention. According to the latter, this movement is provided for byhorizontally slot ting the hole 80 in the jaw through which the pin 77is passed.

The modification shown in Figs. 11, -12 and 13,-of the means forenabling the operator to control the engagement ofthe projection or bolt57 with the pin 58, consists of a socket 81 fast, like the socket 59, onthe elevator 11; the bolt 57; its protruding spring 61; a pin 82projecting from the bolt 57 through and beyond a horizontal slot 83 inthe socket; a rearwardly projecting gravity latch 84 pivoted on the side'of the socket 81 and adapted to latch the bolt 57.

forward and clear of the push pin 58, by engaging behind the projectingportion of the pin 82 as shown in Fig. 11; 85, its pivot; 86, afrontward projection by which the operator can disengage the latch 84from the pm 82 when the line in the elevator 11 is to be quadded; bellcrank lever 87 fulcru'med at 88 on a block 89 fast on the side of theelevator 11 and which block may be shaped to'also discharge the functionof the projection 74 already described and to so replace it, the frontarm of this lever being held in contact with the rear end of the bolt 57and the rear arm projected to the rear beyond 84 engaged behind the-pin82. When the non quadding of the next line.

line in the elevator 11 is to be quadded, he de resses. the rojection86far enough to un atch the bo t 57 which forthwith has its rear endprojected by the spring 61 over the pin 58 with which it engages in theway and with the effect already described. The projection of'the bolt 57makes the bell crank lever 87 throw its rear arm to the rear so as to beengaged and rocked forward when the rise of the elevator 11 after thequadded linotype has'been cast, brings the said rear arm into contactwith-the above mentionedportion 1 of the machine frame, whereby thefront arm of the said lever 87 will push the bolt 57 to the front untilthe pin 82 is in front of the nose of the latch 84 .which thereupondrops behind it and locks the said bolt clear of the push pin 58. Thenose of the latch 84- is beveled so that the pin 82 can raise it as ityis pushed to the front. This provides automatically for the of lines isto be quadded, the projection 86 is depressed far enough to throwthelatch 84- past its pivot 85 to the frontFig. 12

so that it cannot latch the bolt 57 clear of the push pin 58 when ariseof the elevator 11 makes the bell crank lever 87 push the bolt 57 to thefront.

The alternative means illustrated in Figs. 14, 14 and 15, provide forlocking the quadding jaw 17 in its normal position, unlocking ittherefrom, moving it into quadding position, returning it to its normalposition, putting the quadder into and out of action, andquadding aseriesof short lines. They are as follows, taking them. in the abovestated order of their respective. purposes. 91 is a casing fixed uponthe vise top 15 above the normal position of the jaw 17. 92 is a slide.capable of vertical movement only, but in both directions, inantifriction guides 93 within the casing 91. 94 is a cord fast to thebottom of the casing 91 at 95, whence it is led upward over a pulley toa point 100 on the jaw 17where itis made;

101 is a rack fast to the slide ,92. It is shown as on the front of thecasing 91, the connection between-the twoworking in a slot 102 in thecasing. 103 is a longer rack capable of a horizontal movement only insuitable guides 1,04, 104, on the casing 91,

to be either in engagement with the rack 101 and consequently with theslide 92, or to the left of the rack 101 and out of engagementtherewith. 105 .is a link from the rack 103 to the top end of a lever106v fulcrumed on a pin 10? supiported by the casing 91 near the-bottomo it. 108is a engaged with the rack 101.

If a series ceases spring pulling on the lever 106 from a fixed point onthe casing 91 to keep the rack 103 Thus, it is the spring 108 that'holdsthe jaw'17 locked in its normal position. 109 is a bell crank leverlikewise fulcrumed on the pin 107 but independently of the lever 106.110 is a spring adapted to hold this lever 109 in the dotted lineposition shown in Fig. 14. The

lever 109 is turned down to the left by the operator when the jaw 17 isto be unlocked preparatory to quadding, and latched in that position bya catch 111 pivoted on a stud 112 and engaging over a pin 113 projectingto the front from the said lever 109. i

The latter, together with the link 105 and lever 106, are soproportioned and positioned that when the lever 109 is so turned down,its

right arm is in engagement with a stud 114 on the lever 106, while theopposite arm projects' into the downward path of'a lug 115 so positionedon the adjacent side of the elevator 11 that it will engage and depressthe said opposite arm far enough, acting through stud 114,.lever 106 andlink 105, to disengage the rack 103 from the slide 92 just before thesaid elevator has reached its lowest position. Thus it is the downwardmovement of the elevator 11 that unlocks the jaw-17. This jaw isthenmoved into the quadding position by a wei ht 116 dro in freely on theleft side of thc elevatd r 11 and connected to the said jaw by a cord117 passed over a pulley 118 on thevise frame 12.

The weight may be connected to the elevator v 11 by the lug and groovedevice 54, 55 shown in Fig. 6. The jaw 17 is returned by the followingcombination. 119 is a barmounted in the slide 92 so as to slidehorizontally therein in both directions. 120 is a pin passed through thebar 119 and to which 1t is fast, and also through a slot 121 in theslide 92, the length of the slot being propor tioned to the horizontalmovements of the said bar. Each end of the pin 120 carries a roller 122which engages in the respective track 123 in the casing 91. 124, 124,are inclines fast to the respective side of the casing tops of theseinclines project toward the re spective tracks 123 far enough tohold'the bar 119 practically within the casing 91.

91 and facing the respective roller 122 i The 125 isa spring resilientbetween the slide 92 and the bar 119 to kee) its rollers 122, 122, up tothe respective incl as the bar 119 is carried downward by the downwardmovement of, the slide 92, described farther on, the spring 125gradually projects the nose of the bar 119 through a slot in the casing91, far enough for 1t to be engaged by a lug 126 properly positioned onthe elevator 11 to so engage it as the said elevator rises vertically todeliver the line 19 in it. to the distributing'apparatus.

ines 124, 124, so that spring 125, as it is being raised, until it istion.

When the jaw 17 had reached the quadding position, it had pulled theslide 92 downward until the bar 119 was at the level, and the spring 125had protruded it as far as shown by the dot and dash line in Fig. 14. Asthe elevator 11 had reached its lowest position at about the time thejaw 17 had reached its quadding position, the lug 126 is in its lowestposition before the bar 119 is protruded. Consequently, the rise of theelevator 11, first, takes the lug 115 off the lever 109, therebyallowing the spring 108 to pull on the rack 103, and then makes the lug126 raise the bar 119, the inclines 124, 124, pushing it inward againstthe resilience of its clear of the lug 126. The rise of the bar 119carried the slide, 92 up with it, thereby, through the cord 94,returning the aw 17 to its normal position, where it is once more lockedby the spring 108, rack 103 and their connections. Thus it is the risingtop of the elevator 11 that returns the jaw 17, and as one end of thecord 94 is fast and the pulley 96 works in a bight of it, the jaw 17moves two inches for each inch that the slide 92 moves. The slide 92 issuspended from a cord 127 made fast to the top of it at the point 128,led over a pulley 129 supported by the casing 91 above the slide 92 whenit is in its'highest position, and then downward to a spring drum 130 tothe periphery of which it is made fast. The axis 131 of this drum issupported in the casing. 91 and its spring 132 is always turning thedrum to pull the slide 92 upward.

When there is only a single line 19 to be quadded, the operator puts thequadder into action by turning the lever 109 down to the left andengaging the catch 1 11 with its pin 1.13. The quadder is put out ofaction automatically as soon as the lug 115 has disengaged the pin 113from the catch 111, for then the weight of the latter lays it down onits back upon the vise top 15 and the spring 110 returns the lever 109to itsnormal posi- But when. there is a series of such lines tq bequadded, the eatch 111 must be kept up in its operative position inorder that when the lug 115 leaves the lever 109, the latter may bereengage'd with the said catch by the spring 110. The pivot 112 and pin113 are there catch 111 to have two positions, one behind the other, andineither of which, engagement with'the pin 113 is practicable. There isa block 133 standing up from the vise top 15 immediately to the rightof,-preferably, the rear oneof the said two ositions. So, the operator,to put the qua der in action forthe said series, turns the lever 109down and the catch 111 up as before and after he has engaged the said,catch with the pin. 113., he pushes it to therear to the left of the relong enough for the block 133 which backs it up against the tendency ofits own weight to disengage it from the pm 113. When the last line ofthe series hasbeen quadded, the operator moves the catch 111 clear ofthe'block 133 and the quadder is put out of action in the way previouslydescribed.

The alternative means above described do not dispense with the pawls 63,64, 65, and

their connections before described for locking the jaw 17 in itsquadding position against the strain of the justification of the line.

The rack 44' has been described as being either on the jaw 17 or on abar 45 fast to it.v

The bar 45 is fast to the jaw as far as the action of the improvedquadder is concerned,

but it is desirable that the short motion men-- tioned as required ofthe jaw 17 in cotipera tion with the pump stop should not be interferedwith by the said quadder. Accordingly the jaw 17 is connected to the bar45 as shown inFig. 16, by shouldered screws 134 passed through the bar45' or through a lug 135 on it, the lodes 136 in the bar 45 or lu 135(as the case may be) being elongated enough to allow of the jaw 17 .2making thesaid short motion after it has been returned vto its normalposition. The jaw 17 being locked in this position, the weight 116 doesnot pull the said jaw up to a normal line during the time it is beingjustified. The same short motion on the part of the jaw 17 is providedfor when the jaw is moved by the means shown in Figs. 14,14 and 15, byattaching the end ofthe cord 94 to a bar connected to the jaw in the wayjust described.

According to a modification shown inTig. 16, the pawl 46 is disengagedfrom the rack 44 by the bolt 57 engaging the underlying end of a bellcrank lever 137 fulcrumed on the front of the block 78 alreadydescribed, the opposite arm of the lever 137 being connected by a link138 to the right hand end'of the pawl 46 which accordingly has its pivot139 to the left of the point of connection. with the said link. Thespring 140 'to' keep the pawl 46 engaged with the rack 44 is seated in ahole in the top and bottom of the weight 48 after having been led underthe pulley 53Fig. 7- and over a chain wheel 142 axially fast to thefirst of a train. of three gear wheels 143, 144, 145, the last oneengaging with a rack 146 on the bar 45. -The weight 48 pulls the jaw 17into quadding position as soon as the pawl 46 is disengaged from therack 44.

1 It is raised to reverse the train of gears 143 to 145 and the rack 146to return the said jaw into its normal position, by the arm75 alreadydescribed.
